- 1、 利用DCT进行jpg压缩,其中DCT可以调用函数,其它尽量自己编写代码,压缩过程可进行适当简化(通过查书了解jpg的原理); 2、 对图像进行二值化,请利用二值图像压缩方法进行数据压缩,然后解压缩,看通过肉眼能否看清表盘数据,比较两种算法的压缩效果; -1, the use of DCT for jpg compression, which DCT can call the function, the other as far as possible to write your o

- 完善DCT变换,实现对Lena.jpg图像的jpeg压缩。将Lena.jpg图像进行两种以上的方式进行边缘提取,并进行结果分析比较。 -Improve the DCT, compressed jpeg image Lena.jpg. Lena.jpg image, the way two or more edge extraction, and the results analyzed and compared.
JPEG_BaseLine_Encoder
- The JPEG compression scheme is divided into the following stages: 1. Transform the image into an optimal color space. 2. Adjust Aspect Ratio 16:9 3. Digitization Scheme 4:2:0. 4. Apply a Discrete Cosine Transform (DCT) to blocks of pixels
